Thomas & Betts L57-TB – Frequently Asked Questions
1) Is the Thomas & Betts L57-TB conduit body metal or PVC?
Gray iron. That makes it suitable for threaded rigid metal conduit and IMC systems where a nonmetallic body would not be accepted, and the metal body carries the equipment ground path through the threaded hubs. For nonmetallic conduit runs you would use a PVC body instead.
2) What does the L designation on a conduit body like the L57-TB mean for how the conduit turns?
An L body makes a 90 degree change of direction with a removable cover for pulling conduictors, rather than a straight-through pull point. If you need a straight in-line pull use a C body; for a run with a branch take-off you want a T body. The L57-TB is the 1-1/2 inch iron L configuration.
3) What is a Form 7 conduit body and why does it matter which form I buy?
Form number describes the body's internal shape and volume. The L57-TB is a Form 7 body, which is the deeper, larger-capacity casting compared with the shallower Form 5 or Form 8 versions of the same trade size, giving more room for conductor bending space on a pull. Covers and gaskets are form-specific, so a Form 7 body needs a Form 7 cover.
4) Can I use the L57-TB conduit body as a pull point in a long 1-1/2 inch rigid run?
That is what it is for. The removable cover on the 1-1/2 inch iron L body gives you access to pull and reposition conductors at the point the run changes direction, which is why electricians place a body at elbows instead of a sweep on a long pull. Splices are only permitted in a conduit body that is durably marked with its volume, so check the casting before you make up a joint inside it.
